SIGNALING nnvrcn.

Application filed September 12, 1925. -Seria1No. 56,064.

To all whom it may concern:

Be it known that I, DANIEL E. MoIvnn, a citizen of the United States, residing at Duluth, in the county of Louis and State of lVfinnesota, have invented certain new and useful Improvements in Signaling Devices,

of which the following is a specification,

reference being had therein to the accompanying drawing.

This invention relates to signaling devices and has special reference to such nartioular-' ly adapted for use on an automobile vent theft of same.

The principal object of my present invention is to provide a practical and safe housing for such a device.

Other obiects and advantages will appear in the further description of the invention.

Referring now to the accompanying drawing, forming part of this application and in which like reference characters indicate like parts:

Figure 1 is an elevation partly in section of an installation of the device embodying my invention; and

Figure 2 is ton plan view of the whistle housing illustrated in open position.

I am aware that somewhat similar devices have'been employed. that is to sayau alarm whistle associated with the engine of an antomobile' and controlled from the, instrument board thereof, so that this idea broadly does not constitute my present invention.

1 represents the manifold of an automo bile and 2 the instrument or dash board of same. 3 is a whistle of any. well known type having an axial stem4 therein controlline the intake valve 5 in thebottom of the whistle and 6 represents a bell-crank pivotally mounted upon the upper end of the whistle for controlling the stem 4:- To the upner'eud of this bell-crank is attached the rod 7 which is mounted within the pipe or tube 8 leading from the spherical housing 9 about the whistle to the instrument board 2. The rod 7 which projects through the instrument board 2, isprovided with an anto pre is pressed inwardly so that the whistle is in open position will'be engaged by a suitable bolt 19 controlled by the locklO so that on the departure of thelegitimate operator of the car the rod 7 may be pushed inwardly opening the whistle 3 and there locked by the bolt 19, the operator carrying the key which controls same with him, vso that in the event of an unauthorized operator attempting to move the car by the operation of the engine, the whistle will sound the desired alarm; such an arrangement however being old in the art, and further details of construction being unnecessary.

My present invention residesparticularly in the spherical housing 9 made of two semispherical parts hinged as at 11 and each carrying half of an axially disposed externally threaded nipple 12 aboutwhich when the housing is closed the tube 8 is screw-threadedlv mounted as clearly shown in Figure 1, so that, as long as the assemblage is intact it becomes absolutely impossible to obtain access to the whistle and in any way tamper with same. The spherical housing 9 is provided with suitable perforationsso that the sound of the whistle is freely emitted therefrom.

An expansive helical spring13 is shown as installed intermediate of the shoulder 14 on the rod 7 and the end of the nipple 12 to normally hold the rod outboard and the whistle closed.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

i A housing for a signaling device for automobiles comprising two hingedly united semi-spherical members, having a cooperative screw-threaded tube engaging nipple extending therefrom.
